SFAR-S-6TI

Modbus I/O Module
SfAR-S-6TI is designed to be applied wherever multiple points of temperature measurement are required. Supporting a wide range of temperature sensors and thermocouples makes it a perfect choice for, for example, a chemical or power industry. Thanks to 2 digital outputs and pre-installed logic in the module, it can not only be used as a PLC I/O extension, but also as a standalone application controller.

6 Temperature Inputs & 2 Digital Outputs
The module has 6 temperature inputs (TI) and 2 digital outputs (O). Temperature inputs can work with the most popular resistance temperature sensors and a wide range of thermocouples. Digital outputs are NPN transistor outputs. All inputs and outputs are isolated from the logic with optoisolators.

Simplified Configuration and Commissioning Process
A built-in RS485 interface allows an easy connection over the Modbus RTU/ASCII protocol. A 32-bit ARM core processor provides fast processing and communication.
The module is equipped with a set of LEDs used to indicate the status of I/Os, power supply, and RS485 communication.
Configuration of the module is carried out with our free software, the SfAR Configurator. A built-in mini USB allows for performing a primary configuration of the unit without an additional power supply.
To simplify the installation, the module has been equipped with the Quick Connector system. Using a dedicated SfAR-S-LINK cable allows for connecting up to 10 modules, which provide both RS485 communication and external power supply.
